通过对系统能量的收集 使系统的能效达到最大(leakage_minimization_k_user)

完整的射频门禁程序源码包含rc522的驱动程序以及相应的显示程序(There had been many cases about RFID-based access control systems. In this paper, long-distance radio frequency technology was used and image-recognition technology was joined, these technologies were used to realize the automation of access management.)

对MTD雷达中进行杂波滤除的滤滤波器组，就是多普勒滤波器组的仿真 (MTD radar clutter filter filter filter bank, is the simulation of the Doppler filter)

这个程序采用现代谱估计的ARMA参数模型算法对信号的功率谱做了估计(The program uses the ARMA parameter model algorithm of modern spectral estimation to estimate the power spectrum of the signal.)

cdma系统，发射机采用直接扩频序列后发射，接收机采用MMSE接收机(cdma systems, the transmitter after the launch of direct sequence spread spectrum receiver using MMSE Receiver)

说明：  使用Labview平台计算误码率，绘制误码率曲线，用于通信系统仿真。(Calculate the bit error rate and reconstruct the bit error rate curve)

opnet simulation of random access in CDMA network

说明：  正交频分复用（OFDM）信号的互补累计函数(ccdf_of_clipped_foltered_ofdm_signal)

说明：  该软件的处理类似于短时傅立叶变换（STFT），但应用了更长、更重叠的分析/合成窗口，使时频处理从根本上对混叠具有鲁棒性。这种差异与非常活跃的时频处理技术有关，例如Dirac或优化的自适应波束形成器。(The software does processing similar to the short-time Fourier transform , but applies the longer and more overlapping analysis/synthesis window to make the time-frequency processing fundamentally robust for aliasing.)
